Καλώδιο patch Extralink SC/UPC - SC/APC, Singlemode Duplex, G.652D οπτική ίνα, PVC 3 mm, 5 m

Duplex Extralink fibre patchcord with SC/UPC on one end and SC/APC on the other delivers single‑mode transmission over ITU‑T G.652D fibre. The cable has a PVC jacket, 3.0 mm outer diameter and a 5 m length, and is intended for connecting optical equipment, patch panels and FTTH terminations where SC‑style duplex connectivity and single‑mode performance are required.

Advantages

This patchcord combines two SC terminations with different polish types (SC/UPC to SC/APC) to enable flexible mating with equipment using either UPC or APC interfaces while maintaining low back reflection and stable single‑mode signal transfer. The PVC jacket provides mechanical protection and easy handling, and the 3 mm diameter balances flexibility with durability for typical indoor and cabinet installations. The 5 m length reduces the need for additional splicing or extension accessories in data centres, telecom racks and FTTH setups.

Key specifications

How to use

Inspect connector end faces before installation and clean with appropriate fibre cleaning tools to ensure low insertion loss. Route the patchcord along cable management trays or within rack cable organizers, avoiding tight bends and mechanical strain; maintain a bend radius in line with the fibre manufacturer recommendations for 3 mm jackets. Insert the SC connectors into matching SC adapters or ports until a positive click is felt; verify correct mating between UPC and APC interfaces. After connection, test the link with appropriate optical power meters or light sources to confirm signal continuity and acceptable loss.

Recommendations

Store the patchcord coiled loosely and protect connector end faces with dust caps when not in use. For permanent or outdoor exposure, select cables with appropriate UV and weather resistance rather than PVC indoor‑rated jackets. When mixing UPC and APC terminations in a link, be aware of reflection characteristics and use APC where reflection sensitivity is critical (e.g., analog RF over fibre, certain PON deployments).
